Art Blood

Great art must drink deep of the collective unconscious of the particular race-soul from which it gains birth; only when it does THAT does it become in any sense 'universal'.The greatest artists and artworks are the most patriotic;HomerVirgilDanteShakespeareThey are also the most universal, as the call of the Blood resonates in every people.
But try to transfuse the wrong blood type, and the patient dies.

The point is, that greatness knows no moral approval, whether that greatness is Hitler, Nietzsche, or Wagner.
